Fiber Network Cards Engineered Around Our Own Controllers

From the Ethernet controller to the finished adapter, GRT builds the full optical link: server network cards up to 100G, transceivers from 40G to 800G, fiber patch cords and WDM systems — including adapters built on our own G810-2Q, G350AM2 and GRT-201JM chips.

Fiber Network Cards Engineered Around Our Own Controllers

One supplier for the whole optical path

A server link fails or succeeds as a chain: the network card in the slot, the transceiver in the cage, the fiber between racks and the multiplexing that shares it. GRT (Beijing Guang Run Tong Technology Development Co., Ltd.) manufactures across that whole chain, so the card, the optics and the cabling in your bill of materials are specified, tested and supported by one engineering team in Beijing.

The range starts with server network cards — nearly one hundred specifications across gigabit, 10G, 25G, 40G, 50G and 100G, in PCI and PCI-Express form, with single, dual and quad ports. Alongside them sit optical transceiver modules in single-mode, multimode, copper and BiDi variants, AOC and DAC high-speed cables, fiber patch cords in LC, FC and MPO types, fiber media converters and CWDM/DWDM wavelength division equipment.

Adapters built on GRT controllers

Most adapter vendors assemble around the same merchant silicon. GRT additionally designs its own Ethernet controllers, and three of them anchor the current range. The G810-2Q controller (MAC+PHY) drives the FF-1102E-V3.0, a dual-port 100G adapter adapted to both x86 and ARM platforms and to domestic CPU platforms. The G350AM2 powers the FF-902TBP-V3.0 gigabit bypass card, and the GRT-201JM encryption controller sits inside the TYPEC-JM-T USB encryption adapter. Owning the controller means owning the driver roadmap and the long-term supply of the card built on it.

Engineering services behind the catalogue

Standard models cover most deployments, but GRT also runs a custom engineering practice: FPGA hardware and software development, custom-shaped boards, RAID and HBA cards, acceleration and encryption cards, and OEM/ODM production of network adapters. A free loaner testing service lets your team evaluate a card in your own server before committing to a volume order, and support responds around the clock.

What speeds do GRT network cards cover?

The server NIC range covers gigabit, 10G, 25G, 40G, 50G and 100G, in PCI and PCI-Express versions with one, two or four ports. Optical transceivers extend from legacy rates up to 400G and 800G classes.

Can I test a card before ordering in volume?

Yes. GRT offers a free loaner testing service — apply with your server platform details and we will arrange an evaluation unit so your team can validate drivers and throughput on your own hardware.

Do you support domestic Chinese CPU platforms?

The self-developed G810-2Q adapter is adapted to x86 and ARM and to domestic CPU platforms, and selected GRT adapters carry compatibility verification on platforms such as Kunpeng, Phytium, Loongson and Zhaoxin. Ask us for the current verification list for your platform.
